THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 315,759. dated April14, 1885.

Application filed August 6, 1884. (No modeh) To all whom, it mayconcern:

Be it known that I, HARBERT K. Fonnrs, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Combined Thill Couplingand Anti-Rattler for Vehicles, of which the following is aspecification, reference being had therein to the accompanying drawings.

My inyention relates to a combined thillcoupling and anti-rattler forvehicles; and it consists, first, in a concaved metallic plate placedbeneath the shaft-eye and resting upon a rubber cushion supported by atransverse plate, the several parts being adjusted vertically.

It further consists in cars or projections depending from the clip-earsand made integral therewith or inserted therein, said projections beingscrew-threaded and passing through openings in atransverse platesupporting the anti-rattler.

lt lastly consists in means for secu ring the shaft-eyebolt to theclip-ears.

The details of construction and operation of the several parts will behereinafter more fully set forth in the specification, and pointed outin the accompanying drawings, in which Figures 1 and 4 are verticalsections through the axle and clip; Fig. 2, a front elevation of thedevice, and Fig. 3 a transverse section through the coupling andanti-rattler.

The object of the device is to provide an anti-rattler that can beadjusted to the shafteye, so as to give any friction required, and atthe same time be adjusted for wear on the metallic friction-plate.Again, in the thill coupling I desire to dispense with the nut that isgenerally used to secure the bolt passing through the shaft-eye andclipears, and secure said bolt directly to one of the clipears.

Referring more particularly to the drawings, the clip B is secured tothe axle A in The cars B B have depending from them the projections b,let into or made integral with said ears, and which are screw-threadedto receive nuts 0. The exterior ear, B, is screw-threaded to receive thethreaded bolt E, provided with a square head, 0, by means of which itcan be removed The bolt is only so as to engage with the threaded ear B,and is cone -pointed to facilitate its insertion. The shaft-eyes nhaving been secured to the clip-ears by the bolt E, as just explained,the anti-rattler can now be placed in position without using a clamp orjack to force back the rubber packing.

The anti-rattler consists of the metal piece D, coneaved on its upper orhearing side, so as to form a seat for the shaft-eye-n. The lower sidehas two flanges, 2', which hold the rubber cushion F. A transversemetallic plate, 0, having perforations for the passage of theprojections b, is placed underneath the cushion E, and is adj nsted upor down by means of the nuts 0.

It will be observed that by placing the anti-rattler underneath thethill-eye the weight of the thill is taken from the bolt, and there istherefore less wear on the bolt and thill-eye than when the anti-rattleris placed between the thill and axle, as is usually the case.

The plate 0 can be tightened up, so as to obtain any degree of frictionagainst the eye a, by the metal piece D, and wear upon said piece can becompensated for. As the bolt E is tapped into the ear B, there is nodanger of drawing in the ears and binding the thill-eye, so as to causewear on both, as is the case with the ordinary thill-couplings Whereajam-nut is used on the inner end of the bolt. A thill-coupling Ina lein this manner and pro vided with the adjustable anti-rattler affords aready means for replacing the said anti-rattlers by simply removing thenuts 0.

Having thus described my invention, what I claim is- 1. In athill-coupling, the clip ears B B", one of which is screw-threaded, asdescribed, and both provided with projections b, in combination with thethreadedbolt E, substan tiall y as and for the purpose set forth.

2. In a thill coupling, the combination, with the clip-ears, one ofwhich is screwthreaded. said ears having the projections 11, of thepointed bolt E, the metallic piece D, a rubber cushion and transversesupportingplate 0, substantially as described, and for the purpose setforth.

In testimony whereof I affix mysignature in presence of two witnesses.
